Summary:
This diff does a couple things:
- Undo redo with a new undo/redo store that maintains it's own queue of undo/redo tasks. This queue is separate from the TaskQueue because not all tasks should be considered for undo history! Right now just the AddRemoveTagsTask is undoable.
- NylasAPI.makeRequest now returns a promise which resolves with the result or rejects with an error. For things that still need them, there's still `success` and `error` callbacks. I also added `started:(req) ->` which allows you to get the underlying request.
- Aborting a NylasAPI request now makes it call it's error callback / promise reject.
- You can now run code after perform local has completed using this syntax:
```
task = new AddRemoveTagsTask(focused, ['archive'], ['inbox'])
task.waitForPerformLocal().then ->
Actions.setFocus(collection: 'thread', item: nextFocus)
Actions.setCursorPosition(collection: 'thread', item: nextKeyboard)
Actions.queueTask(task)
```
- In specs, you can now use `advanceClock` to get through a Promise.then/catch/finally. Turns out it was using something low level and not using setTimeout(0).
- The TaskQueue uses promises better and defers a lot of the complexity around queueState for performLocal/performRemote to a task subclass called APITask. APITask implements "perform" and breaks it into "performLocal" and "performRemote".
- All tasks either resolve or reject. They're always removed from the queue, unless they resolve with Task.Status.Retry, which means they internally did a .catch (err) => Promise.resolve(Task.Status.Retry) and they want to be run again later.
- API tasks retry until they succeed or receive a NylasAPI.PermanentErrorCode (400,404,500), in which case they revert and finish.
- The AddRemoveTags Task can now take more than one thread! This is super cool because you can undo/redo a bulk action and also because we'll probably have a bulk tag modification API endpoint soon.
Getting undo / redo working revealed that the thread versioning system we built isn't working because the server was incrementing things by more than 1 at a time. Now we count the number of unresolved "optimistic" changes we've made to a given model, and only accept the server's version of it once the number of optimistic changes is back at zero.
Known Issues:
- AddRemoveTagsTasks aren't dependent on each other, so if you (undo/redo x lots) and then come back online, all the tasks try to add / remove all the tags at the same time. To fix this we can either allow the tasks to be merged together into a minimal set or make them block on each other.
- When Offline, you still get errors in the console for GET requests. Need to catch these and display an offline status bar.
- The metadata tasks haven't been updated yet to the new API. Wanted to get it reviewed first!
Test Plan: All the tests still pass!
